Muscle memory the term was first coined in the gay scene which many thought was coined in the bath houses of san Francisco and the fact there is a scene amongst the community to work it so it is not known as to whether it was said to be the fact like my Bruars and a hag he said that it means the ability to bounce back with working out after taking time off as my bruar will tell you it is a state of mind getting buff with his husband but it is not sure if the term muscle memory stems from a lot of gay activity which some press say can be a hundred comoings and goings a night and it is thought this is why Muscle Memory came about as the Spinkter becomes a memory and long gone is its twitching days awaiting pleasurement.
